I've just begun working OGL with Python and had a question about PIL.
Specifically, I've been using it to load .png's as textures, and now have a need
to draw other images (.jpg, .png) as background images. I'm interested in using
something along the lines of:
glPixelStorei(GL_UNPACK_ALIGNMENT,4);
glRasterPos2i(0,600)
glDrawPixels(800,600,GL_RGBA,*someBitmapSet*)
But I am unsure as to how to get the *someBitmapSet* out of the object returned by
someImage.tostring("raw", "RGBA", 0, -1)
image = numarray.array(numarray.fromstring(image, numarray.Byte))
I've tried glDrawPixels(800,600,GL_RGBA,GL_UNSIGNED_BYTE,image) to no avail.
Is this possible? Am I headed in the right direction?
You shouldn't be using glDrawPixels.. it's almost always slow. You want to draw it to a texture, and then render the texture to a rect. There are examples out there for getting a PIL image into an OpenGL texture, but I can't think of anything off the top of my head.
